Sally invites you to go on a long journey with her into space in her small spaceship of mass 1000kg. Using thermodynamics approach, she tells you that stellar bodies can be assumed to have an average mass of 10^30kg ( mass of the sun ), and to move with a random velocity of 10 km/s. She wants to know the average velocity the rocket will reach after a very long time. You asked her, "what happens if we fall into a star?" She tells you to neglect the possibility of that happening.
